Cl. 7-8.1 8 Claims ABSTRACT OFTHE DISCLOSURE There is provided a portable combination tool intendedfor manual use in penetrating barriers occurring in such disasters asthe, collapsed buildings and the like, into the region of which it isdiflicult to carry a plurality of special tools. The combination toolconsists of two parts, each provided with its respective shaft capableof being collapsed telescopically one within the other, and which can belocked together in different extended or collapsed positions. Oneportion of the tool is provided with an axe-and-pick head and alaterally projecting crow bar and suspension loop, while the otherportion of the tool is provided with forked leg members, shaped to forma chisel-like member and a cutting tool respectively, and wherein saidtool portions can also be used as a wedging means and a hammer.

The present invention is concerned with a portable combination toolintended to replace a plurality of special tools intended forpenetrating barriers of metal, wood, glass, plastics, rubber and lighterforms of brickwork in conjunction with such catastrophic incidences asfire, collapsed buildings and the like, where weight and space preventthe necessary assortment of special tools to be carried into the regionof the disaster. The working operations which might be required in suchincidences include hewing, prizing, wedging, pulling, lifting, striking,cutting and propping. I

The tool of the invention is provided with a plurality of tool elementsadapted to effect the aforementioned working operations wherewith, inaddition to having at immediate disposal the tool necessary for theimmediate task on hand, the capacity of the tool to effect the task canbe strenghtened by increasing the length of the shaft in a simplemanner, without the length of said tool being unsuitable for carryingpurposes.

The invention is mainly characterized in that the tool consists of twoparts, each having its respective shaft, the shafts being collapsibletelescopically one within the other, one tool portion having an axe headpresenting an axe blade and an oppositely directed spike, and projectinglaterally from one side of the head is a lip adapted to be used as acrow bar, and in the opposite lateral direction there is provided aloop, while the other portion of the tool is provided with claw-like legmembers of which one is shaped at the end thereof to form a chisel-likemember and on the other side is provided with a saw-toothed edge, andthe other leg has a cutting edge confronting the saw-toothed edge, thelegs together forming a cutting tool having wedge-shaped sides, and thatthe shaft has cooperating locking means so adapted that the shafts canbe locked to each other when telescoped and in a limited extendedposition, and that the shafts are movable but not rotatable between theend positions and can be dismantled from each other by mutual rotationin the extended position.

The invention will now be described in more detail with reference to theaccompanying drawing, further characterizing features of the inventionbeing disclosed in conjunction therewith.

3,623,173 Patented Nov. 30, 1971 In the drawing:

FIG. 1 is a partially sectioned side view of the tool of the invention,

FIG. 2 is a longitudinal section through the line II-II in FIG. 1, and

FIG. 3 is a section along the line III'III in FIG. 1.

In the drawing there is illustrated the tool of the invention having atone end an axe portion 1 which at one side of the tool shaft presents ablade 2 furnished with a cutting edge 3 and tooth-like serrations 4, 5on the upper and lower long edge thereof, adapted to facilitate removalof objects etc., and on the opposite side of the shaft presents a spike6 for making holes etc. The bottom edge of the spike 6 is provided witha cutting edge 7 to enable a hole made with the spike 6 to be split andwidened. The head of the axe portion 1 also presents a laterallyprojecting, wedge-shaped lip 8 which can be used for bending andlevering purposes, e.g. to bend up flooring, and which, owing to thefact that the upper side 9 of the axe head is formed so that the toolcan grip and roll on an abutment surface, affords a high bending force.Furthermore, there are disposed at right angles to each other in the axehead holes 10, 11 for a purpose which will be explained below. The sideof the axe head positioned opposite the lip 8 is in the shape of a yoke12 which can be used for hanging up the tool during transport and forengaging ropes, metal sheets etc. The shaft of the axe consists of atube 13 which is attached to the axe head and on which a handle 14 madeof rubber, plastic or the like is fitted. At the end of the shaft 13there is welded a steel ring 15 into which is tangentially inserted apin 16.

The other portion of the tool, the claw portion 17, is telescopicallymounted for movement in the shaft 13 of the axe portion. The clawportion 17 consits of a rod 18 having a diameter slightly smaller thanthe inner diameter of the tubular shaft 13 and presenting a planarsurface 19 along the majority of its length, and adjacent the free endthereof is arranged a circumferentially extending groove 20, and beyondsaid groove a planar surface 21 on the side opposing the surface 19. Theclaw portion 17 is fixed to the end of the rod 18 and is shaped to forma fork-like member, one leg 22 of which forms a chisel-like memberpresenting a saw-toothed edge 23, while the other leg 24 presents anedge 25 confronting the edge 23, the legs between them forming aY-shaped cutting tool intended, for instance, for loosening or cuttingbolts or the like. Arranged on the side surface of the claw portion isan abutment surface 26 which enables the claw portion 17 to be used as ahammer. The legs 22 and 24 are wedge-shaped to enable the claw portionto be used for wed ging and levering operations.

The tool can be used with both tool portions combined, or each separateportion of the tool may be used per se for different tasks.

When assembling the two tool portions to form a combined tool, the endof the rod 18 is insetred in the ring 15 with the planar side 21 facingthe pin 16, and is inserted until the movement is stopped by the edge ofthe groove '20 meeting the pin 16. The width of the groove 20 is adaptedto the thicknes of the pin 16 to enable the rod 18 to be turned one-halfrevolution, whereby the planar surface 19 is turned to face the pin. Inthis position the rod 18 can be pushed fully home into the shaft 13. Toretain the claw portion 17 in the inserted position, a locking pin 27having a spherical end is mounted in the axe head 1, wherewith bydepressing the pin 27 the spherical end of said pin can be moved into aspherical recess 28 in the rod 18. The locking pin 27 is retained inlocking or free position by means of a spring-loaded ball 29. The recess28 is so positioned that the claw 17 in its inserted position presents asmall clearance to the ring 15, and to release the locking pin 27 thetool is held by the axe portion 1 and the claw portion 17 struck againsta hard surface to force said portion further into the shaft 13,whereupon the locking pin 27 is forced out of the recess 28 and the rod18 is released. The ball 29 holds the pin out of engagement until it isre-pressed into engagement with the pin. 27 when assembling the two toolportions to a single combination tool.

As a result of the coaction between the pin 16 and the planar surface 19arranged on the rod 18, it is impossible to separate the two toolportions unintentionally. With the locking member 27 in free position,the claw portion 17 can thus be applied to an object and the axe portionused as a hammer tool by impact of ring 15 against the flange on theclaw portion 17. The shaft is extended by withdrawing the claw portion17 until the pin 16 engages in the groove 20 and then rotating theportion 17 through 90, thus providing the axe 2 or the spike 6 with anincreased impact force or a longer lever when bending with the clawportion 17.

The diameter of the holes 10 and 11 are such that the end of the rod 18can be inserted in either of said holes so that the two tool portionsform an angular support which, for instance when wishing to lift heavyobjects to a small extent, can be used in a manner whereby the clawportion 1'7, inserted in the hole 11, constitutes a support for the axehead, around which a line or other support means can be attached. Thesupport can also be used to prevent a collapse of the structure ofnarrow passages.

The field of use of the tool is naturally not restricted to thoseaforementioned, but the tool can be used in all situations when it isrequired to rapidly penetrate a closed passage, a wrecked car etc., andin many other forms of rescue and salvage work.
